Check Gradation

The Check Gradation feature allows you to print gradated color patch prints for

each line screen on the digital press. These gradated color patch prints are used

to verify that the dry ink/toner densities for CMYK and Grey balance are correct.

If you are dissatisfied with the appearance of any color on the print, you can

manually adjust the dry ink/toner densities for Cyan, Magenta, Yellow, and Black

using the Manual Adjust feature. It is recommended that you begin your

calibration by calibrating the 300 PG screen first. This is the basic line screen

that is used, and all other line screens are calibrated against the 300 PG screen.

Use this feature daily and compare the output of gradated color patches to the

color patch prints from the previous day. Under normal operating conditions,

there should be no difference between them. Automatic sensors and control

mechanisms in the digital press with scanner should maintain consistent

calibration.

If there is an obvious visual difference between two days’ color patches, run the

calibration process on the Raster Image Processor, then run this gradation

process again.
